Does anyone know an internet location contain shareware (or freeware) software to allow me to communicate to some I2C controlled PIC projects using the PC's parallel port. What I'm needing is some sort of test software to evercise the various building blocks individually. Would really like source code in C of C++ but that might be asking too much. Got any ideas ... thought as this group before I started writing what I needed myself. Thanks Larry ----------------------------------------------------------------------- Larry P.
